I don't believe the old bits (WinFX Beta 1, CLR Beta 2 etc.) are being maintained anymore.
Is it possible for you to move to Windows Vista Feb CTP? That way you can use Feb CTP versions of WinFX and the development tools for WinFX. The latter will provide project template support for WinFX applications.
Windows Vista Feb CTP is available only to MSDN Subscribers, while the tools etc. are available to everyone. The "Get the Beta" page is a good starting point.
